virtualenv: Builtin creation follows linked environment directories
影響: pip:virtualenv < 21.14.9 → 21.14.9 The builtin creator accepts existing directory symlinks through ensure_dir() and writes environment files through those directories. This permits writes outside the requested destination. Anthropic's OSS Scanner reported this as ANT-2026-MUFJEG11 in virtualenv-20261015-005, received on 15 October 2026. Affected area Directory preparation before environment files are created. Attacker-controlled input Another account must be able to prepare linked entries below the chosen destination before crea…
virtualenv: Deletion recovery can change a symlink target's mode
影響: pip:virtualenv < 21.14.9 → 21.14.9 The deletion error handler obtains permission bits with lstat() but applies them through chmod(), which follows symlinks. On an eligible unlink failure this can change permissions outside the destination. Anthropic's OSS Scanner reported this as ANT-2026-UK90QC27 in virtualenv-20261015-005, received on 15 October 2026. Affected area Permission recovery after a filesystem deletion error. Attacker-controlled input A deletion must fail on a symbolic-link entry and enter the permission-recovery bra…
virtualenv: Generated POSIX console launchers interpret destination paths as shell syntax
影響: pip:virtualenv < 21.14.9 → 21.14.9 A destination path supplied to virtualenv can be interpreted as shell syntax by a generated POSIX console launcher. The app-data seeder and pip delegate launcher generation to distlib but supply the interpreter path in a form that does not preserve it as literal data in the shell wrapper. Affected area POSIX console scripts generated by the app-data seeder or pip when the interpreter path requires a shell wrapper. Windows executable launchers are not affected by this path. Attacker-controlled i…
Pillow: Memory disclosure and segfault in libtiff encoder via crafted TIFF tags
影響: pip:Pillow <= 12.3.0 → 13.0.0 ============================================================================ Memory disclosure and segfault in libtiff encoder via crafted TIFF tags Location: src/encode.c:1014 in PyImaging_LibTiffEncoderNew() Commit: a707c6b21c313880d0771e54965d142dd42358b6 ============================================================================ A crafted TIFF file of a few hundred bytes makes Pillow copy an attacker-chosen amount of its own process memory into the TIFF it writes back out, or crash the pro…
Pillow: Heap buffer overflow in _tiffWriteProc when saving TIFF to BytesIO
影響: pip:Pillow >= 2.0.0, < 13.0.0 → 13.0.0 ============================================================================ Heap buffer overflow in _tiffWriteProc when saving TIFF to BytesIO Location: src/libImaging/TiffDecode.c:94 in _tiffWriteProc() Commit: a707c6b21c313880d0771e54965d142dd42358b6 ============================================================================ Pillow can write attacker-chosen data past the end of a heap buffer when it saves a TIFF image to an in-memory destination such as io.BytesIO rather than to a file. The…
Pillow: Heap use-after-free when encoding TIFF to an in-memory buffer
影響: pip:pillow >= 11.3.0, < 13.0.0 → 13.0.0 Saving an image as TIFF to an in-memory buffer can trigger a heap use-after-free if libtiff rejects a tag at encode time. When TIFFWriteScanline fails, the encoder frees its output buffer but leaves the libtiff handle open. Later, when the encoder object is torn down, TIFFClose flushes buffered bytes through the write callback and writes into the freed buffer. An application that re-encodes attacker-influenced images to TIFF in memory can be crashed and is a candidate for remote code execution.…
Pillow: Infinite loop in PdfParser.rewrite_pages on page tree Parent cycle

Pillow: APNG background disposal allocates full canvas before decompression bomb check
影響: pip:Pillow >= 8.1.0, < 13.0.0 → 13.0.0 ============================================================================ APNG background disposal allocates full canvas before decompression bomb check Location: src/PIL/PngImagePlugin.py:1000 in PngImageFile._seek() Commit: a707c6b21c313880d0771e54965d142dd42358b6 ============================================================================ A 126-byte animated PNG file makes Pillow's Image.open() allocate and fill memory sized by the image dimensions the file claims, before Pillow's built-i…
Pillow: MSP RLE decoder expands a tiny file into unbounded memory
影響: pip:pillow >= 4.1.0, < 13.0.0 → 13.0.0 The MSP RLE decoder expands run-length data into an in-memory buffer with no cap tied to the declared image size. A small file that passes the pixel-count check can force hundreds of megabytes or more of allocation when the application loads pixels. Details The MSP decoder writes each run into an unbounded io.BytesIO and can expand roughly 85x per run: - src/PIL/MspImagePlugin.py:144-146 Impact Memory-exhaustion denial of service from a tiny crafted image in any application that loads pixels. T…
Pillow: Quadratic-time DoS in PDF save_all (PdfParser.next_object_id)
影響: pip:Pillow >= 5.1.0, < 13.0.0 → 13.0.0 ============================================================================ Quadratic-time DoS in PDF save_all (PdfParser.next_object_id) Location: src/PIL/PdfParser.py:629 in next_object_id() Commit: a707c6b21c313880d0771e54965d142dd42358b6 ============================================================================ Pillow's PDF writer takes time proportional to the square of the number of frames when it saves a multi-frame image as a multi-page PDF.

Pillow: PdfParser can recurse without limit in get_value() and linearize_page_tree()
影響: pip:Pillow >= 5.1.0, < 13.0.0 → 13.0.0 PdfParser's get_value() can recurse without any limit and crash with an uncaught RecursionError. It is reachable through Image.save(im, fp= , format="PDF", append=True) when the existing PDF file is attacker-controlled. This is the same class of bug as https://github.com/advisories/GHSA-r73j-pqj5-w3x7 (the /Prev trailer chain loop, fixed earlier this year), in the same file, but in two different functions that fix did not touch. Details get_value() in src/PIL/PdfParser.py This is a clas…
Pillow: ReDoS in XbmImagePlugin: 512-byte file stalls Image.open() for minutes
影響: pip:Pillow <= 12.3.0 → 13.0.0 ============================================================================ ReDoS in XbmImagePlugin: 512-byte file stalls Image.open() for minutes Location: src/PIL/XbmImagePlugin.py:58 in XbmImageFile._open() Commit: a707c6b21c313880d0771e54965d142dd42358b6 ============================================================================ A crafted 512-byte file makes Pillow's Image.open() spend about six minutes of processor time on one core before it gives up with UnidentifiedImageError. Anyone w…
Pillow: Image.quantize() with empty palette leaks uninitialized stack memory
影響: pip:Pillow >= 9.1.0, < 13.0.0 → 13.0.0 ============================================================================ Image.quantize() with empty palette leaks uninitialized stack memory Location: src/libImaging/Palette.c:216 in ImagingPaletteCacheUpdate() Commit: a707c6b21c313880d0771e54965d142dd42358b6 ============================================================================ When an application lets a user supply the palette image for Pillow's Image.quantize(palette=...), the user can get back 512 bytes of the server process's st…
Pillow: Quadratic GIF comment concatenation allows DoS in Image.open()
影響: pip:Pillow >= 5.4.0, < 13.0.0 → 13.0.0 ============================================================================ Quadratic GIF comment concatenation allows DoS in Image.open() Location: src/PIL/GifImagePlugin.py:266 in GifImageFile._seek() Commit: a707c6b21c313880d0771e54965d142dd42358b6 ============================================================================ Opening a crafted GIF file with Image.open() takes time that grows with the square of the file's size, so anyone who can submit an image to a service that uses Pillow ca…
Pillow: Infinite loop in MIC n_frames when the embedded TIFF
影響: pip:Pillow >= 7.2.0, < 13.0.0 → 13.0.0 ============================================================================ Infinite loop in MIC n_frames when the embedded TIFF has 3+ IFDs Location: src/PIL/MicImagePlugin.py:86 in MicImageFile.tell() Commit: a707c6b21c313880d0771e54965d142dd42358b6 ============================================================================ A crafted 5.6 KB image file makes Pillow loop forever at 100% CPU when an application asks how many frames the image has. This only affects installations that have the o…
Pillow: Quadratic GIF comment copying during save
影響: pip:pillow >= 9.2.0, < 13.0.0 → 13.0.0 On Pillow 12.3.0 and upstream main (ad277e2761b489681e71b51e91367d46b0ceabb9), a GIF with a long comment makes _get_global_header() copy portions of the comment repeatedly when saving, including comments carried over from untrusted images. I suggest provisional Moderate severity for crafted-image CPU denial of service, with CVSS-B 6.9 assuming a network service automatically opens unauthenticated uploads and they are resaved as GIFs; impact depends on input-size, concurrency, and worker CPU lim…
Pillow: NULL dereference in ImagingExpand via rank filters on zero-size images
影響: pip:Pillow <= 12.3.0 → 13.0.0 ============================================================================ NULL dereference in ImagingExpand via rank filters on zero-size images Location: src/libImaging/Filter.c:79 in ImagingExpand() Commit: a707c6b21c313880d0771e54965d142dd42358b6 ============================================================================ Applying Pillow's median, minimum, maximum or rank filter to an image with zero width or zero height crashes the whole Python process instead of raising an error. Empty…
Pillow: NULL pointer dereference in Image.merge via an unvalidated band 0
影響: pip:pillow >= 12.0.0, < 13.0.0 → 13.0.0 Image.merge() checks the mode of every input band except band 0. If band 0 is a single-band I or F image, the native merge routine reads a pixel pointer that is NULL for those modes and the process crashes. The IPTC plugin reaches this from a plain Image.open() followed by a load, and IPTC has no magic-byte prefilter, so a crafted file with no recognizable header can drive it. Details The validation loop skips band 0: - src/PIL/Image.py:3795 iterates for band in bands[1:] and checks mod…
Pillow: Invalid free in FreeType glyph rendering when a stroker is active
影響: pip:pillow >= 10.0.0, < 13.0.0 → 13.0.0 When text is drawn with a non-zero stroke width, Pillow creates a FreeType stroker and then loads each glyph. If FT_Load_Glyph fails for a glyph, the cleanup path calls FT_Done_Glyph on the glyph variable. That variable is not initialized before the first measurement loop, and in the render loop it is not reset to NULL after each glyph is freed. A malformed font loaded from untrusted bytes can force the load error and reach this free. This is a latent memory-safety defect; whether it cr…
Pillow: Double free in ImagingScaleAffine on calloc failure via Image.transform
影響: pip:Pillow <= 12.3.0 → 13.0.0 ============================================================================ Double free in ImagingScaleAffine on calloc failure via Image.transform Location: src/libImaging/Geometry.c:866 in ImagingScaleAffine() Commit: a707c6b21c313880d0771e54965d142dd42358b6 ============================================================================ There is a double free in Pillow's Image.transform() that crashes the process when an oversized transform runs out of memory. Instead of only raising MemoryErro…
Pillow: P;2L and P;4L decoders may read 1 to 3 bytes past the passed buffer size
影響: pip:Pillow <= 12.3.0 → 13.0.0 On main, even with the guard in #9725, it's possible to have these decoders read 1 to 3 bytes past the end of the passed buffer with a suitable width/height. Details ImagingRawDecode and the P;2L / P;4L unpackers disagree about how many bytes a line of data occupies. The raw decoder derives the line size from the bits per pixel c state->bytes = (state->xsize state->bits + 7) / 8; and uses it both for the bounds check and to advance to the next line. For P;2L and P;4L, bits is 2 and 4 re…
Pillow: Argument Injection in Ghostscript call, potentially leading into RCE
影響: pip:Pillow >= 2.6.0, < 13.0.0 → 13.0.0 PIL.EpsImagePlugin.Ghostscript() builds the Ghostscript command line using the input file path (fp.name) without sanitization, placing it at -f . A filename beginning with - is interpreted by Ghostscript as an option, giving command-line argument injection; chainable to RCE (see Impact). Reproduces with Pillow's default invocation (with -dSAFER enabled). Details _Give all details on the vulnerability. Pointing to the incriminated source code is very helpful for the maintainer._ Type CWE…
pypdf: Unvalidated JPEG image data loading
影響: pip:pypdf < 6.21.1 → 6.21.1 An attacker who uses this vulnerability can craft a PDF which leads to arbitrary image parsers being called. This requires loading an image which claims to use the /DCTDecode filter (JPEG data). Users which do not have the optional Pillow dependency installed in their environment are not affected. Patches This has been fixed in [pypdf==6.21.1](https://github.com/py-pdf/pypdf/releases/tag/6.21.1). Workarounds If you cannot upgrade yet, consider applying the changes from PR [#4222](https:/…
Vitest: Servers misapply `server.fs.deny`, serving `.env`, private keys, `.git`, and the API token file
影響: npm:@vitest/ui >= 5.0.0-beta.6, < 5.0.5 → 5.0.5, npm:@vitest/browser >= 5.0.0-beta.6, < 5.0.5 → 5.0.5, npm:vite-plus >= 1.0.0-rc.0, < 1.3.0 → 1.3.0 In Vitest 5, Vite's server.fs.deny is not applied as intended on Vitest's dev servers. Depending on the server, files that Vite refuses to serve by default (such as .env, private keys and certificates, .npmrc, and .git) or Vitest's own API token file (.vitest-secret-token) can be read over plain HTTP by a client that can reach the server. In Browser Mode with test.projects, a malicious website can also read .env values through the developer's browser. This only applies when Vitest runs…
Vitest: Code injection via unauthenticated manual mock registration
影響: npm:@vitest/mocker >= 2.1.0-beta.7, < 4.1.12 → 4.1.12, npm:@vitest/mocker >= 5.0.0-beta.1, < 5.0.3 → 5.0.3 @vitest/mocker's interceptorPlugin accepts mock registrations on Vite's dev-server WebSocket with no authentication, and interpolates the mock's url into generated module source without escaping. A client that can reach the dev server can make it serve arbitrary JavaScript in place of any project module, which then runs in the developer's browser on the dev-server origin. Same handler and same unauthenticated caller as GHSA-82fw-gwwq-j7x9; that fix (8ff9b9a9efca7c6cfd5243569440de8d7a33a…
Vitest: Windows backslash traversal bypasses the @vitest/mocker redirect allowlist fix
影響: npm:@vitest/mocker >= 4.1.11, < 4.1.12 → 4.1.12, npm:@vitest/mocker >= 5.0.0-rc.2, < 5.0.3 → 5.0.3 The path traversal fix released for [GHSA-82fw-gwwq-j7x9](https://github.com/vitest-dev/vitest/security/advisories/GHSA-82fw-gwwq-j7x9) can be bypassed on Windows by using a backslash in the redirect URL pathname. The fixed code joins an attacker-controlled URL pathname with the Vite root using node:path/posix, then passes that string to Vite's file allowlist check. On Windows, a value such as C:/project/root/..\secret.txt retains ..\ during the POSIX join and begins with the allowed ro…
ApostropheCMS: Exposure of Sensitive Information via predictable export filenames
影響: npm:@apostrophecms/import-export < 3.7.1 → 3.7.1 When a user exports content through @apostrophecms/import-export, the module copies the generated archive into uploadfs at /exports/ and returns a public URL under /uploads/exports/. The filename is fully deterministic: site shortName, document type, a YYYYMMDDHHmmss timestamp, and the format extension. There is no secret token. Anyone who can guess that path can download the archive with a normal unauthenticated HTTP GET while the file is still present (10 minutes by default, longer if…
OpenClaw: Browser CDP discovery could accept blocked WebSocket URLs
影響: npm:openclaw < 2026.6.6 → 2026.6.6 Browser CDP discovery could accept blocked WebSocket URLs. In affected versions, a lower-trust caller or configured input path could reach network destinations that should have been blocked by OpenClaw policy. This advisory is scoped to the named feature and configuration. It does not change OpenClaw's trusted-operator model: authenticated Gateway operators, installed plugins, and intentional local execution surfaces remain trusted unless a separate policy, approval, allowlist, sandbox,…
Storybook: Missing origin validation in Storybook preview allows code injection from malicious websites
影響: npm:storybook >= 8.0.0, < 8.6.19 → 8.6.19, npm:storybook >= 9.0.0, < 9.1.21 → 9.1.21, npm:storybook >= 10.0.0, < 10.6.2 → 10.6.2, npm:storybook >= 11.0.0-alpha.0, < 11.0.0-alpha.6 → 11.0.0-alpha.6, npm:@storybook/core >= 8.0.0, < 8.6.19 → 8.6.19, npm:@storybook/core-server >= 8.0.0, < 8.6.19 → 8.6.19, npm:@storybook/experimental-addon-test >= 8.0.0, < 8.6.19 → 8.6.19, npm:@storybook/addon-vitest >= 9.0.0, < 9.1.21 → 9.1.21, npm:@storybook/addon-vitest >= 10.0.0, < 10.6.2 → 10.6.2, npm:@storybook/addon-vitest >= 11.0.0-alpha.0, < 11.0.0-alpha.6 → 11.0.0-alpha.6, npm:@storybook/addon-mcp >= 10.6.0, < 10.6.2 → 10.6.2, npm:@storybook/addon-mcp >= 11.0.0-alpha.0, < 11.0.0-alpha.6 → 11.0.0-alpha.6 Summary: A malicious website may be able to cause unauthorized file changes in a developer’s project while an affected Storybook development server is running. Under additional conditions, a changed file could be executed by a local runtime with the developer’s privileges. We are not aware of exploitation in the wild. Who is impacted? You are impacted if you run a Storybook dev server in the affected versions. You are not impacted if: - You run a dev server that you never open in a web browser…
Electron: HID and USB permission checks can be attributed to the wrong origin
影響: npm:electron >= 45.0.0-alpha.1, < 45.0.0-alpha.5 → 45.0.0-alpha.5, npm:electron >= 44.0.0-alpha.1, < 44.3.0 → 44.3.0, npm:electron >= 43.0.0-alpha.1, < 43.7.0 → 43.7.0, npm:electron < 42.11.3 → 42.11.3 For hid and usb permission checks made from an iframe, session.setPermissionCheckHandler was given the top-level frame's origin and details instead of the requesting frame's. Apps that allow these permissions based on origin could grant an embedded frame access intended for the top-level page. You're only affected if you use setPermissionCheckHandler with origin-based logic for hid or usb and embed cross-origin iframes with allow="hid" or allow="usb". Apps that don't delegate those featu…
djust: Arbitrary absolute-path file read in the find_handlers_for_template MCP tool
影響: pip:djust >= 0.9.0, <= 1.0.9 → 1.0.10, pip:djust >= 1.1.0, <= 1.1.6 → 1.1.7, pip:djust >= 1.2.0.dev0, <= 1.2.3 → 1.2.4, pip:djust >= 1.3.0.dev0, <= 1.3.0rc7 → 1.3.0rc8 Affected version / file / line Version: djust v1.1.4 (latest release, published 2026-09-23).

ApostropheCMS: POST /api/v1/@apostrophecms/doc/slugTaken discloses existence of private/admin-only content to any authenticated user
影響: npm:apostrophe < 4.34.0 → 4.34.0 The slugTaken endpoint returns a boolean indicating whether a slug is in use across all document types and visibility levels, with no permission or type filter. Any logged-in user (including editors) can enumerate the slug space of private pages, drafts, and archived content. Details POST /api/v1/@apostrophecms/doc/slugTaken with body { "slug": "target-slug" } runs a raw existence check against the documents collection. It does not: - Check whether the requesting user has read permissio…
ApostropheCMS: GET /api/v1/@apostrophecms/page/:id bypasses viewRole restriction and exposes viewPermission-gated fields to lower-privileged users
影響: npm:apostrophe < 4.34.0 → 4.34.0 The getOne REST endpoint for pages does not apply viewRole type-level restrictions or viewPermission field-level redaction. An editor-level user who knows a document _id can read the full content of admin-only pages and their privileged fields, while the getAll endpoint correctly enforces both restrictions. Details Finding 3 — viewRole bypass: modules/@apostrophecms/page/index.js exposes getRestQuery(req, omitPermissionCheck = false). The getAll path calls publicApiCheckAsync and thread…
ApostropheCMS: Stored XSS via Unescaped Widget Style Attribute Serialization
影響: npm:apostrophe < 4.34.0 → 4.34.0 ApostropheCMS widget styles support project-defined schema fields. If a project defines a free-form string style field with a CSS property and no selector, an editor-controlled value is rendered as an inline CSS declaration. The resulting declaration is then inserted into the widget wrapper's style="..." attribute without HTML-attribute escaping. An attacker who can edit the widget can include a double quote in the style value, terminate the style attribute, and inject new HTML event-ha…
ApostropheCMS: Missing Authentication in `cleanExport` Route
影響: npm:@apostrophecms/import-export < 3.7.1 → 3.7.1 1. Summary The API endpoint POST /api/v1/@apostrophecms/import-export/clean-export in @apostrophecms/import-export lacks authentication and authorization checks. Any client—including unauthenticated anonymous users who have obtained the standard CSRF cookie from visiting the site—can directly invoke this route and trigger the underlying self.cleanExport(req) method. --- 2. Affected Files & Endpoints Endpoint: POST /api/v1/@apostrophecms/import-export/clean-export Route Definition: packages/impo…
ApostropheCMS: Unauthenticated publicApiProjection bypass via search and sort query builders in the public REST API
影響: npm:apostrophe < 4.34.0 → 4.34.0 ApostropheCMS lets a module expose an anonymous read API by setting publicApiProjection, which whitelists the document fields unauthenticated callers may see. The public REST GET handler applies every launderable query builder from the query string before forcing that projection. Two of those builders, search and sort, operate on the underlying documents rather than the projected output, and neither is checked against the projection. An unauthenticated attacker can therefore: - use ?sea…
ApostropheCMS: Color field validation bypass allows stored XSS via HTML appended after rgb()/hsl() prefix
影響: npm:apostrophe < 4.34.0 → 4.34.0 The color field accepts any string that begins with a valid rgb() / hsl() color, because TinyColor.isValid does not anchor its match at the end of the string. An authenticated user with edit rights can store arbitrary HTML after a valid color prefix. When the stored value is rendered , the payload executes, resulting in stored XSS. Details Server-side validation of the color field relies on TinyColor: js const { TinyColor } = require('@ctrl/tinycolor'); if (!new TinyColor(value).isValid…
ApostropheCMS sanitize-html: unbounded recursion when re-sanitizing the fallback of a discarded iframe (stack overflow, nestingLimit not enforced)
影響: npm:sanitize-html >= 2.18.0, < 2.18.1 → 2.18.1 Since 2.18.0, when an is not allowed and disallowedTagsMode is 'discard' (the defaults), its raw-text content is re-sanitized by a recursive call to sanitizeHtml(text, options) (the change from #5564, fixing #5550). The recursion has no bound and starts each nested call with a fresh state. Two consequences, both absent from 2.17.7 and 2.17.4: 1. A few kilobytes of unclosed tags throw RangeError: Maximum call stack size exceeded with the default options. Any application that sanitizes un…

影響: pip:pypdf < 6.20.1 → 6.20.1 An attacker who uses this vulnerability can craft a PDF which leads to an infinite loop. This requires removing an object from a tree, for example an outline item. Patches This has been fixed in [pypdf==6.20.1](https://github.com/py-pdf/pypdf/releases/tag/6.20.1).

pypdf: Possible infinite loop when hitting EOF in standard xref table
影響: pip:pypdf < 6.20.0 → 6.20.0 An attacker who uses this vulnerability can craft a PDF which leads to an infinite loop. This requires an incomplete file which ends inside the xref table. Patches This has been fixed in [pypdf==6.20.0](https://github.com/py-pdf/pypdf/releases/tag/6.20.0). Workarounds If you cannot upgrade yet, consider applying the changes from PR [#4170](https://github.com/py-pdf/pypdf/pull/4170). Notes This has been reported through both the secure channel and as a public issue at [#4169](https://gith…
virtualenv bash activate runs commands from an environment name with a backslash before $
影響: pip:virtualenv <= 21.14.6 → 21.14.7 The bash activate script escapes the environment name for only one of the two passes bash makes over PS1, so a backslash in the name undoes the escaping and a name containing \$(...) runs as commands in the user's shell each time bash draws the prompt. Affected area src/virtualenv/activation/bash/activate.sh, the block that prepends the environment name to PS1. Attacker-controlled input The environment name: the environment directory's name, or the --prompt or VIRTUALENV_PROMPT value. A…
pypdf: Possible large memory usage for streams with multiple filters
影響: pip:pypdf < 6.20.0 → 6.20.0 An attacker who uses this vulnerability can craft a PDF which leads to large memory consumption. This requires accessing any stream with a large amount of filters or multiple filters which pass around large amounts of data. Patches This has been fixed in [pypdf==6.20.0](https://github.com/py-pdf/pypdf/releases/tag/6.20.0). Workarounds If you cannot upgrade yet, consider applying the changes from PR [#4173](https://github.com/py-pdf/pypdf/pull/4173).
Vite: Cross origin script execution through Vite custom middleware
影響: npm:vite >= 8.3.0, <= 8.3.2 → 8.3.3, npm:vite >= 8.2.0, <= 8.2.3 → 8.2.4, npm:vite >= 8.0.0, <= 8.1.5 → 8.1.6, npm:vite >= 7.0.0, <= 7.3.6 → 7.3.7, npm:vite <= 6.4.3 → 6.4.4, npm:vite-plus <= 1.0.0 → 1.1.0 When accessing a malicious site while a dev server using Vite is running, that site was able to load scripts in a page served by the dev server. Impact Only apps that match the following conditions are affected: - the dev server passes an unchanged browser request URL to server.transformIndexHtml: this is normally used for server.middlewareMode: true or appType: 'custom'. The internal call for appType: 'spa' and appType: 'mpa' does not match this. - the transformed HTML contains an inli…
Vite: Files outside `server.fs.allow` could be served when project paths match system paths on non-Windows machine
影響: npm:vite >= 8.3.0, <= 8.3.2 → 8.3.3, npm:vite >= 8.2.0, <= 8.2.3 → 8.2.4, npm:vite >= 8.0.0, <= 8.1.5 → 8.1.6, npm:vite >= 7.0.0, <= 7.3.6 → 7.3.7, npm:vite <= 6.4.3 → 6.4.4, npm:vite-plus <= 1.0.0 → 1.1.0 The content of files outside server.fs setting can be returned to the browser if the project imports a file path concatenated with the root. For example, if the project references /etc/hosts, the content of /etc/hosts was possible to be returned. The content of files outside the server.fs.allow option can be returned to the browser when a project imports a file whose root-relative path matches an absolute path on the host. For example, referencing /etc/hosts could make Vite return the h…
Vite: First 4 bytes of files outside of `server.fs` setting is exposed by `?vite-wasm-instance`
影響: npm:vite >= 8.3.0, <= 8.3.2 → 8.3.3, npm:vite >= 8.2.0, <= 8.2.3 → 8.2.4, npm:vite-plus >= 0.2.8, <= 1.0.0 → 1.1.0 The first 4 bytes of files outside of server.fs setting can be returned to the browser by a request containing ?vite-wasm-instance. Impact Only apps that match one of the following conditions are affected: - explicitly expose the Vite dev server to the network using --host or the [server.host](https://vite.dev/config/server-options#server-host) option - there's a file that has a sensitive information in the first 4 bytes - uses Node.js or Deno to run Vite (if Bun is used, it is not affe…
virtualenv activate runs commands from the environment name in zsh with PROMPT_SUBST
影響: pip:virtualenv <= 21.14.3 → 21.14.4 zsh users activate an environment with the bash activate script, which puts the environment name into PS1. Since 21.13.0 the script escapes backslashes, dollar signs and backticks in that name, but only when BASH_VERSION is set, so zsh gets the raw value. With the PROMPT_SUBST option set, zsh runs parameter expansion, command substitution and arithmetic expansion on PS1 each time it draws the prompt. A name that contains $(...), backticks or ${...} then runs as commands in the user's she…
